Abstract:

Large groups of young men were exposed to high intensity pulse trains at 2.5 kc and examined continuously for subsequent acuity changes at 4 kc. Duty cycle varied from 3.4 tone-on to 100, train length from 1-25 min., and sound pressure level SPL from 90-120 db. A new unit, the NOX, representing total cumulative fatigue over a 10-min. interval, was invented to describe the results.
